A radio frequency integrated circuit includes a transmitter section, and a
receiver section. The receiver section includes a low noise amplifier,
down conversion module, an orthogonal-normalizing module, and a baseband
processor. The low noise amplifier is operably coupled to amplify the
inbound RF signals to produce amplified inbound signals. The down
conversion module is operably coupled to convert the amplified inbound RF
signals into baseband in-phase components and baseband quadrature
components. The orthogonal normalizing module is operably coupled to
obtain a 1.sup.st and 2.sup.nd coefficients that are based on at least
one of power of the baseband in-phase components, power of the baseband
quadrature components, and/or cross-correlation between the baseband
in-phase component and baseband quadrature components. The orthogonal
normalizing module then normalizes an orthogonal relationship between the
in-phase components and quadrature components based on the 1.sup.st and
2.sup.nd coefficients to produce normalized in-phase components and
normalized quadrature components.
